摘　　要：右室流出道是特发性室性心律失常易起源位置,右室流出道起源的室性期前收缩占所有室性期前收缩的80%以上。起源于该处的特发性室性心律失常经射频导管消融治疗的成功率在75%~100%,而且并发症风险低。右室流出道解剖上毗邻左室流出道,尤其是主动脉窦,又是致心律失常性右室心肌病心脏发育不良三角的一部分,其自身又分为前间隔、后间隔和游离壁,术前对此区体表心电图的鉴别诊断尤为重要。Idiopathic arrhythmias arising from the right outflow tract are the most common subtype of idiopathic ventricular arrhythmias, and more than 80% of premature ventricular contractions originate from the right ventrieular outflow tract. The acute success rate for ablation of right ventrieular outflow tract-ventricular arrhythmias ranges from 75 to 100% with a low risk of complications. Anatomically, right ventricular outflow tract is adjacent to left ventrieular outflow tract, especially aortic sinus, and as a part of the triangle of arrhythmogenie right ventricular cardiomyopathy,it is divided into anterior septum, posterior septum and free wall. It is particularly important to analyse the electrocardiogram before radiofrequency catheter ablation.
